A milk-maid had been to the meadow to milk her cows. Now she was returning  home with a pail of milk on her head. She thought, "I will make cream and butter out of this milk. then selling  them, I will buy eggs. and when they hatch, I shall have a good poultry  farm." She further thought, "I shall sell some of my fowls and buy a fine dress. seeing it on my body at the fair, all the boys will admire me. but  I will turn them away just tossing my head at them." Lost in day dreams, she forgot about the pail on her head. She tossed her  head with a jerk and the pail of milk came tumbling down. It was broken and  all the milk got spilt. "Dear o dear !" She cried, "I have lost my all." 
Don't count your chickens before they are hatched.
